How to Add My Maiden Name to Facebook
Facebook is an effective way to find old friends and catch up with acquaintances you haven't seen in a long time. As a married woman, however, you probably use your husband's last name, making it difficult for people to find you if they only know you by your maiden name. Thankfully, Facebook provides a way for you to update your profile to display your maiden name alongside your married name.
Log into Facebook.
Click "Account," and select "Account Settings" from the drop-down menu.
Click "Change" next to "Name."
Type your maiden name in the box next to "Alternate Name." Select "Include this name on my profile" if you want to display your maiden name. Otherwise, your maiden name is logged simply so other users can find you through a Facebook search.
Click "Save Changes" to confirm.
